1 Claim.

The invention relates to building construction, and more especially, to a concrete building construction.

The primary object of the invention is the provision of a building construction of this character, wherein there is employed a minimum of material, and general economy had in the erection thereof, and neatness in appearance, as well as ease in such erection, the construction being intended principally for small structures, granaries, garages, poultry houses, implement houses, tourist cabins, or the like.

Another object of the invention is the provision of a building construction of this character, wherein it is made from prefabricated concrete materials, and its foundation is such to support the light weight of the edifice, this foundation being only deep enough to rest on virgin soil and to avoid possibility of the soil being washed away and thus leaving no support, and the heaving by freezing taken care of by bearings and gaskets between the walls of the edifice and the said foundation, and between the said walls and roof, as well as through slight flexibility or give permitted by tying wires between the wall panels and the pilasters.

A further object of the invention is the provision of a building construction of this character, which is simple in construction, thoroughly reliable and effective in its purposes, strong, durable, readily and easily erected, and inexpensive to erect or install.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which show the preferred and modified forms of construction of the invention, and hereinafter pointed out in the appended claim.

In the accompanying drawings Figure 1 is a perspective view of a building constructed in accordance with the invention.

Figure 2 is a fragmentary sectional view taken on the line 2-2 of Figure 1 looking in the direction of the arrows.

Figure 3 is a sectional view taken on the line 3-3 of Figure 1 looking in the direction of the arrows.

Figure 4 is a sectional view taken on the line 4--4 of Figure 1 looking in the direction of the arrows.

Figure 5 is a fragmentary top plan view of the roof area.

Figure 6 is a sectional view taken on the line 2 B6 of Figure 5 looking in the direction of the arrows.

Figure '7 is a sectional view taken on the line 1-7 of Figure 2 looking in the direction of the arrows.

Figure 8 is a sectional view taken on the line 88 of Figure 1 looking in the direction of the arrows.

Figure 9 is a sectional view taken on the line 99 of Figure 1 looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A designates generally a flat walled building construction, in its entirety, constructed in accordance with the invention, comprising a foundation of sill formation It made from set concrete materials, molded or otherwise created, and borders a floor slab l l of set concrete, which is part of such foundation, the sill formation it employing enough concrete to support the light weight of the building, and need only be deep enough to rest on virgin soil and to avoid possibility of the soil being washed away, leaving no support.

Rising from the sill formation it throughout the four or more vertical walls of the building are the prefabricated concrete panels 52, which are arranged vertically, edge-to-edge with respect to each other, and in the lowermost edges of each panel 12, next to the sill formation II) is a groove-like seat l3 into which is received a correspondingly shaped lockin rib it built upon the formation Ill, while interposed between the seat and rib is a bonding gasket I5.

The panels H2 at their vertical edges next to each other are formed with external reversely, beveled surfaces is to effect a seating trough at their meeting, to accommodate a lap joint weather stripping I'l made from concrete, the stripping being formed with an inner face it corresponding to the surfaces it for true interfitting and snug assembly of the panels and such stripping. The outer face it of the stripping is rounded, yet it may be otherwise.

Embedded in the stripping l? are the twisted ends 20, which are interlocked with each other, of reinforcing wires 2| embedded within the panels I2, and this stripping ll carries the ends 20 during the molding or otherwise forming of the said stripping in its placement.

overhanging the panels I 2 are the prefabricated roofing panels 22 made from concrete, which are arranged in edge-to-edge sections and in reversely sloping groups inclined from a medial ridge cappin piece 23 made from concrete, and superimposed thereon at the ridge joints, where the panels 22 meet and are interlocked by a tongue and groove connection 24 with each other. The points of contact of the wall panels l2 and the roofing panels 22 are interlocked by tongue and groove connections 25 with an interposed bonding gasket 20 therebetween.

The panels 22 at their meeting edges are formed with upturned flanges 21 which are interfitted in companion seats 28 provided in the under face of overlapping joint strips 29, of concrete, as-best seen in Figure 9 of the drawings. The. strips 29 are pocketed at 39 in the capping piece 23, as

best seen in Figure 2 of the drawings. The tongue and groove connections 24' 'inclu'dea-bonding gasket 3|.

Horizontally built between the wall panels l2 atthe interior space of'the building A is a lay of rafters, a portion of one being denoted at 32, which is made from wood, and the end of'the said rafter next to the wall panels 12 bridges the joint between those adjacent to each other, and has coupling with such .panels and the stripping H by a loop-like bail. tie 33 which is embedded in such stripping and passed through clearances in the panels [2, for bolting at 34 to the said rafter. The bail tie 33 is held in the stripping IT by a key 35, as best seen in Figure 7 of the drawings. The panels 22 are provided with wire reinforcements 36, and likewise, the capping piece 23 carries reinforcement wiring 51, this being also true with respect to the strips 29, which reinforcements are indicated at 38.

The bearings and gaskets between the walls and foundation and between the walls and roof-- ing, as well as the slight flexibility or give permitted by the tie wires tying the wall panels to the pilastels takes care of heaving b freezing during cold weather.

What is claimed is:

In a building of the character described, the combination of a pair of concrete panels lying in a common plane in edge-to-edge contact with each other, adjacent edges of said panels having beveled surfaces, respectively, convergingtoward each other to form a substantially V-shaped trough having the apex thereof in the plane of contact of said adjacent panel edges, a concrete stripping having a substantially V-shaped portion interfitting said trough and bridging said pair of panels, a key embedded in and lengthwise of said stripping, a substantially U-shaped bail tie having a bight portion and a pair of leg portions, said tiebight portion being about said key and embedded in said stripping, said tie leg portions extending from said bight portion and through said panels, respectively, a rafter abutting said panelsand bridging the joint between the same, said rafter beingreceived between said tie le portions andmeans securing said leg portions and'means securing said leg portions to opposed portions respectively, of said rafter whereby said stripping, adjacent panels and rafter are rigidly united into an unitary structure.
